' g m r LIFE-SAVING DEVICE;

To all wltomhtmay concern Be it'known that LFnOnosv LAvaYK, a citizen of Russia, residing at Ch cago,

county. of Cook, and State of Illinois, have invented certain new and useful Improvements in Life-SavingrDevices, of which the following is a specification. This invention relates to accidents on the water: generally.

a novel arrangement :and combination of parts by which the person using the life;

preserver will be thoroughly protected from the waves and have an abundant air supply at all times, and in addition to be able to propel and steer himself or herself along the surface of the water and show a night signal which Wlll serve to guide searches.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompany ng drawings, and to the appended clalms 1n wh ch the various novel features of the lnventlon are more particularly set forth.

Figure 1 of the drawings is a plan view of a life preserver constructed according to my invention.

Fig. 2 is a side elevation thereof 7 Fig. 3 is an enlarged detail vertical section of the valve controlling the air intake 1 e. p Fig. 4 is a longitudinal sectional view of the device. I

Fig. 5 is a perspective View of the propeller.

As here shown my improved life preserver comprises an oblong casing nclosmg a main compartment 2, a subsidiary casing member 3 inclosing a compartment bemg secured on one end of the casing. Apartition 5 extends in a general diagonal di- "Specification of Letters Patent.

Secured nponthetoplof casing 1 the straps 10 1s anairhbag 11 which extends substantially thefull length of the casing.

Air may be supplied continuously to air I bag 11 to keep the latterjproperly inflated The invention has for an object to provlde by a pipe 12:1eadingfrom, anvairpump-13 of ordinary reciprocating. type having its.

bottom thereof. This lever arm has rigid therewith an operating handle 17 which projects upwardly in the compartment 2. Air enters pump 13 through a pipe 18 which 7 extends upwardly beside the casing, termlnatlng a desired distancethereabover The upper end of this pipe is provided with a one-way ball valve 19 pushed upwardly against a suitable seat on an apertured head 20 on the top of the pipe by a spring 21. This spring is disposed in a boring 22 in the valve into which the end of a pin 23 projects freely. This pin projecting upwardly from a disk 24 fixed in the pipe 18 and having apertures 25 therein. A hollow I cap 26 surrounds the upper end of pipe 18 to prevent accidental striking of waves.

against the valve 19, this cap being supported on posts 27. From the air bag 11 a ipe 28 leads to the compartment 41.

n addition to the piston rod 14, the lever arm 15 has connected thereto one end of a .3

pitman rod 30 which extends rearwardly' ed to be operated by pressure of the users foot, this lever engagingja slot 39 in the clutch member 36.

To steer the device a rudder 40 is mounted on the underside of the. casing 1 near the in the casing and having an offset 38 adaptrear end thereof and has secured to the stern thereof, which projects into the casing l, a cross bar 41 adapted to be engaged by the feet of the user. An electric battery 42 is secured to the under side of the casing 1 and from it wires 13 and 44 lead to an electric light 45 mounted on the top of the air ba 11.

s will be apparent, when the user is in position he can grasp the handles 17 and operate the pump to supply air to the bag 11 and to-the compartment 4; for breathing purposes. The propeller 32 may be worked in unison with pump 1-3 or not asdesired by pressing on the short arm of bell crank lever with the foot, while the rudder 40 may also be worked by pressure of the feet on the cross bar 41.

Having thus described my invention what.

I claim as new and desire to secureby Letters Patent of the United Statesis as foling, a subsidiary casing, a :rubber sheet apertured to receive the head of the user separating said caslngs, an airbag secured on top of said main casing, an electric lamp mounted on top of the said air bag, a battery secured to the main casing supplying electric current to said lamp, a pump carried by the main casing and adapted. to supply air to said air bag and subsidiary casing, a propeller mounted on the rear end of the main casing and adaptedto be operated in unison with said pump, and steering means carried by said main casing.

In testimony whereof I have afiixed my signature.
